Archer Aviation spent years promising to fly you across a city in a whisper-quiet electric air taxi. At Farnborough this week it revealed something rather different: a pilotless, hybrid-electric tiltrotor built with the defence-technology firm Anduril, big enough to haul cargo into places a helicopter would rather avoid. The commercial version is called Halo. Its military twin, shown two days earlier, is called Thunder. They share one airframe and one very deliberate idea — take the best of the eVTOL boom and point it at jobs that have nothing to do with commuting.

Where Archer’s piloted Midnight air taxi runs on batteries and carries four passengers across town, Halo is fully autonomous, runs a series hybrid-electric powertrain for far greater range, and is designed to lift heavy payloads with no one aboard. No pilot means no human exposed on a dangerous run, lower cost per flight, and an aircraft that can work around the clock.

One airframe, two badges

The clean-sheet design is the product of an exclusive partnership Archer and Anduril struck back in December 2024, aimed squarely at a future US defence programme and backed by a $430 million raise. Anduril’s Lattice software handles the autonomy. Two “optimum-speed” tiltrotors vary their RPM to cut power draw and noise in cruise, giving the aircraft vertical take-off and efficient, runway-independent range.

Halo’s commercial pitch is unglamorous and potentially enormous: offshore energy resupply, time-critical freight, humanitarian and medical cargo into places without runways. Japan’s Marubeni Aerospace signed on as launch partner. Archer says full-scale surrogate aircraft have already flown, with the first flight of the production machine targeted for 2027.

A complement, not a replacement

Archer is careful to say Halo does not push aside Midnight, which remains its priority as it grinds through FAA certification for US passenger service. Instead, the company has quietly widened its ambitions: the same engineering that promised to unclog city skies is now being aimed at logistics, disaster relief and, through Thunder, the battlefield. Whether the market rewards a pilotless cargo tiltrotor is the open question — but the bet is placed.
